Evaporation is even greater if the air is dry and hot. Tus a constant supply of water should be made available. Soring the flowers in a vase with water can help with this. Te xylem tissue in the floral stem then transports water from the vase to the floral bud. I the flower is cut in the air, te air bubbles enters the xylem and block it. Tis will lead to blockage of the only water transport route to the floral bud. I has been shown previously (Jones, the air bubbles usually settled down in the xylem about 2 cm from the opening.

Tus in order to get rid of the air bubble, oe may re-cut the stem inside the water; ding this will help getting rid of the air bubble. Aother source of xylem blockage is the bacteria in the water itself. Tese bacteria proliferate over time and block the xylem and will also lead to foul smell. Tus in order to avoid that, wter containing one-teaspoon chlorine per lit water can be used. Clorine is and keeps the bacteria count low.

Wter temperature is important for the blooming. Cld water is useful in the hot weather. I keeps the flower cooler and thus delays its development and death. Smetimes it could be necessary to use warm water around 40oC especially in the case of severely dehydrated flowers as it passes quickly through xylem. p of the water avoids bacterial growth too. ApH of around three is acidic and keeps the contamination away. Aart from this, te acidic water passes quickly through xylem. Vnegar a source to reduce the pH.

A the flower is cut from the plant, i needs a source of energy. Te best way is to add sucrose to the media. 2 sucrose is usually sufficient for a normal floral development. Nvertheless, sgar in the media also promotes bacterial growth, tus it is important to lower the pH and to add disinfectant as well. Ehylene is a plant hormone – a gas that is produced in the flower. Ecessive ethylene can hurt the flower. Frtunately it is possible to the ethylene in the flower by storing them at lower temperatures.

Fur-week-old plants were bought at a local plant nursery ensuring that they are all of same age and treated exactly the same way. Ater bring them home, tey were treated exactly the same way for 48 hours before cutting the flowers. Al cut flowers for the experiments were stored in separate vase in a room with ambient light. Fesh air circulation was insured through an. ..
